The MIDI channel is what the switch shows plus one, i.e. 0 = channel 1, 9 = channel 10, A = channel
11, F = channel 16. When the UM2 is turned on, the display shows the actual channel number; the
switch can then be rotated and the display shows the current channel.

3) Connect MIDI
(see page 9 for MIDI connector pinout)
Connect MIDI IN to your source (i.e. MIDI OUT of computer, synthesizer, or other MIDI device).
4) Connect Outputs
Connect your outputs to the 40-pin headers in the back of the UM2 (see page 10 for pinout); optionally
use our terminal adaptors (see page 5).
5) Connect Power supply
The UM2 requires 7 to 25 volts power supply; this is usually tapped from the main supply of your
system. The negative of the power supply connects to the NEG pins of the 40-pin headers in the back of
the UM2 (see page 10 for pinout); in most cases this is also ground of the system. We recommend that
all NEG pins connect to the power supply negative; this is simplified if you use our terminal adaptors
(see page 5).
The positive of the power supply (5-25 volts) connects to the POS pins of the 40-pin headers in the back
of the UM2 (see page 10 for pinout); usually, this is also the common to all the relays or switches in the
system. The UM2 is a positive driver, it switches its outputs to POS; we recommend that all POS pins
connect to the power supply positive; this is simplified if you use our terminal adaptors (see page 5).
Introduction
The UM2 is a MIDI decoder-driver: it receives MIDI messages and activates its outputs accordingly.
The outputs can be used to drive organ pipe relays, lamps and other accessories.
The UM2 has two internal partitions (the UM2-64 has only one). Each partition can be used
independently as 64 outputs with each a different MIDI channel; or the two partitions can be combined
into a single 128 output partition.
Installation
In the following sections, the examples show organ manuals (keyboards) and organ pipes (with relays)
connected to UM2s. These are just the most common items used with the UM2; here are a few examples
of what the UM2 can control:
• Other musical instruments such as trumpets, xylophone, bells, drums, etc…
• Electric lights, with or without relays, depending on voltage/power
• Garage doors, alarm systems, model trains…
Other control applications involving a computer

UM2 Manual

Requirements
Power: the UM2 requires power from an external source; this is usually tapped from the main supply of
your system. The voltage must be between 5 and 25 volts. The current used by the UM2 is less than 0.3
amps.
MIDI: the UM2 receives MIDI, so it must be connected to a MIDI device; a computer, synthesizer…
Computer (optional): for diagnostics and software setup, a PC with Windows 95 or Windows 3.1 and a
MIDI port is required.
Stand-alone configuration
The simplest system is the stand-alone configuration. In the following diagram, two UM1s are connected
to manuals (keyboards), generating MIDI note messages from keys. Each UM1 corresponds to a UM2
with the same MIDI channel. Two UM2s are receiving the MIDI notes, driving the pipe relays.
The limitation of this system is the one-to-one correspondence between keys pressed and pipes playing.
Most organs need to be able to play multiple pipes for one key pressed.
Another stand-alone example is the addition of ranks of pipes to a synthesizer system; those ranks would
be equipped with relays and UM2s, connected to the MIDI OUT of the synthesizer. The pipes would
play when the player sets the synthesizer’s output channel to the UM2’s MIDI channels.
Computer controlled configuration
This is the most powerful and flexible installation. All the MIDI note messages generated from the
keyboards go through the computer before they control the relay drivers.
3
UM2 Manual
 2001
This system allows recording and playback with sequencing software.
Up to 16 UM2s can be daisy chained on a single MIDI cable. In practice, we keep this number lower,
because of the MIDI delay: every note message takes about one millisecond (0.001 sec) to be transmitted
on the cable. This is not a problem on the console side, a single MIDI cable can keep up with ten fingers
and two feet. But on the pipes side, if one key, for example, could activate 10 pipes, 5 keys pressed
simultaneously can cause a delay of 0.050 sec, which is noticeable. If this applies to your system, you
should have multiple MIDI output ports on your computer (we suggest 2 to 8 ranks of pipes per MIDI
port, depending on the flow).
Setup of UM2 relay driver
The function of the UM2 is to receive MIDI note messages and drive its outputs accordingly.
Choose partitions and transpose with the MODE switch (see chart page 9) or software setup (see page 6).
For example, switch 1 ON and all other switches off would be a single partition of 128 outputs.
The UM2 outputs are connected to relays, solenoids, valves, lights or other resistive/inductive loads (see
specification page 8 for maximum load). The UM2 outputs are active high (positive driver), which
means they act like a switch to the positive of the power supply (see diagram below); therefore the relays
are connected between the UM2 outputs and the negative of the power supply.
The positive of the power supply must connect to “POS” (see chart page 10).
The negative of the power supply must connect to “NEG”, pin 1 of the 40-pin connectors; in most cases
this is also ground of the system. We recommend that all POS and NEG pins connect to the power
supply. If you are using our optional screw terminal blocks TERM1-128 or TERM1-64, the those pins are
already brought together to a single terminal.
No “clamping” diodes are necessary, the UM2 contains diodes from NEG to each output.
Vibrato output:
The vibrato output is a slow oscillator whose frequency is controlled from zero to 10 pulses per second,
by MIDI Modulation Bender messages (see page 13). This output can
be used to control a door or device that modulates the sound.

Connecting with screw terminal blocks
Wiring is simplified with our optional screw terminal blocks TERM1-128 or TERM1-64, which bring out
all the outputs where they can connected directly to your wires.
Another option is the solder terminal blocks TERM1S-128 or TERM1S-64, which bring out all the
outputs where they can soldered to your wires:
The diagram below shows screw terminals for 128 outputs, connected to a UM2 or UM1.

Operation
Power up
When power is applied to the UM2, its display should light up, showing the version number for half a
second, and then the channel number. If the display does not light up, see troubleshooting, page 7. If the
power up diagnostics are enabled at the MODE switch (see chart page 9), a message will be displayed if
an error occurs.
You can change the channel at any time by rotating the switch labeled CH.
The MIDI channel of the source should match that of the UM2. If you have two partitions, the number
displayed is the channel of partition A; partition B may have a different channel, according to the MODE
switch (see chart page 9) or software setup (see page 6).
Operation
During operation, the left dot on the display lights up when receiving MIDI messages on the assigned
MIDI channel, the right dot when transmitting messages.
You should rarely need to use the buttons:
The RST is the reset button, like the one on a PC; use it if things are locked up, or if you need to read
the version number, which is displayed for half a second after reset is pressed.
The OK button will clear an error message on the display: when an error occurs, the display will blink
with the message “Er” followed by one or two numbers (see error chart page 7).
Installing the UM2 software
To install the UM2 setup/diagnostics software on your PC, insert the diskette and run the file called
“setup”.

UM2 Manual
 2001
Software setup / diagnostics
As an alternative to using the MODE selector switch, the UM2 can be configured with the UM2
setup/diagnostics software which gives a few more options. To enable software setup, the MODE
switches must all be ON; this is not necessary for diagnostics.
Connect the UM2’s MIDI IN to the PC’s MIDI OUT and the UM2’s MIDI OUT to the PC’s MIDI IN
(actually, several UM2’s can be chained together as in the diagram page 4. You may be able to change
the setup without removing the units from your installation).
Power up the UM2, and run the UM2 setup/diagnostics software.
The software will attempt to find the UM2(s) on your MIDI port, and will give you the choice between
setup or diagnostics.

partitions, the number displayed is the
channel of partition A; partition B may
have a different channel, according to
the MODE switch (see chart page 9) or
software setup (see page 6)
MIDI OUT of the source should
connect to MIDI IN of the UM2

Notes out of range
Output polarity
One output does not respond
Bad relay
Short
Depending on the MODE switch or
software setup, you may call for
transposition. Without transposition,
the first output is MIDI note zero.
Notes out of range do not activate
outputs.
The UM2’s outputs switch to the
positive side of the power supply, so
the other side of the relay (or light or
voltmeter) should be connected to the
negative of the power supply.
Check that relay, swap it for a known
good one
Check wiring of this output
